CARBOLON™
Carbon Fiber Heat Insulator
Felt Laminated FGL Series
FGL Series are manufactured by
impregnating resins into regular soft
felts.
These products can be used over
2,000℃ and have good insulation
capability and easy installation for
insulation structure.
Purified FGL series are the most
suitable for applications where
impurities should be limited.
Based upon each application, we
machine, make surface treatments
and purity it.

1）Flexural strength
This shows the strength when perpendicular
load is put on two supports.
2）Compressive strength
This shows the strength when perpendicular
load is charged on both sides.
3) Coefficient of thermal expansion
This shows representative numbers measured
between the room temperature and 500℃.
4）Thermal conductivity
These numbers are obtained by NCK ‘s
steady-state method.
